6. What is the working principle of a dump trailer?

The hydraulic lifting system of the dump semi trailer is composed of fuel tanks, hydraulic pumps, distribution valves, lifting hydraulic cylinders, control valves and oil pipes and other components.

The working principle is: the tractor engine drives the hydraulic pump through the transmission and the power take-off device, the high-pressure oil enters the lifting hydraulic cylinder through the distribution valve and the oil pipe, and pushes the piston rod to tip the carriage. By controlling the movement of the piston rod through the operating system, the carriage can be stopped at any desired inclined position. After the cargo is unloaded, the compartment is reset by its own gravity and hydraulic control system.

It is worth mentioning that the YUHANG brand dump trailer can be equipped with an electro-hydraulic lifting system, which can be lifted quickly and smoothly, and can be controlled with a remote control, which has higher safety.

All of our dump semi trailers for sale use high-quality Chinese famous brand HYVA hydraulic cylinders, which have the characteristics of strong lifting force, high lifting height, and fast unloading.

7. What are the components and structures of the dump semi trailer:

Dump Semi Trailer Structure

Dump semi trailer is mainly composed of compartment, chassis, hydraulic lifting system, sub-frame, landing gear (support device), suspension, axle (axle assembly), electrical circuit, protective net, tool box and other components.

1. Compartment

It is mainly used to restrain the loaded goods. The box body is made of high-strength cold-rolled steel plate, which has strong bearing capacity, large space, and no permanent deformation.

2. Chassis

The high-strength performance and complete steel chassis reinforced and welded by the center beam can flexibly cope with the load-bearing gravity. With solid road suitability, it can run safely on many poor road surfaces.

3. Hydraulic Lifting System

Manipulate the power take-off device of the gearbox of the tractor to drive the hydraulic pump to work. The hydraulic pump sucks the hydraulic oil in the hydraulic oil tank through the low-pressure oil inlet pipe and generates high-pressure oil for output. The high-pressure oil output by the gear pump enters the lift valve through the high-pressure oil pipe, and lifts Under the control of the air control valve, the valve sends high-pressure oil to the cylinder or discharges it into the hydraulic oil tank to realize the lifting, stopping and lowering functions of the hydraulic cylinder.

4. Landing Gear

The device used to support the front load of the 3 axle tipper trailer price that is separated from the tractor is composed of a base, a pull rod transmission mechanism, an inner square tube, an outer square tube, a gearbox, and a control handle.

5. Suspension

8. What are the features of YUHANG dump trailer?

The main features of YUHANG dump trailer are:

(1) Low center of gravity

The sub-beam at the bottom of the carriage adopts the Omega structure, which is organically combined with the main beam of the chassis, which reduces the height of the load-bearing surface and the center of gravity of cargo loading, and improves the safety and stability of the vehicle.

(2) Optimized design structure

Advanced computer-aided design software is used to optimize and analyze the vehicle structure, and the chassis structure is scientifically designed by using tracking data, and the load is divided reasonably to ensure that the trailer always has the best load-bearing performance.

(3) Lightweight frame

Lightweight frame, optimized load rating. The scissor brace and double web structure are adopted in key parts. It ensures the structural strength while reducing the weight, increases the stability of the car body lifting, and greatly reduces the risk of rollover.

(4) High-strength steel

The carriage floor and side panels are made of high-strength steel, which has the advantages of wear resistance and impact resistance. Improve trailer application ability and prolong service life.

(5) New specification accessories

10. How to improve the safety of dump trailers?

Due to the heavy weight, large blind spots and difficult braking of dump semi trailers, the losses caused by accidents are unimaginable. Therefore, customers should not only pay attention to their own needs but also ensure that they have absolute safety before purchasing dump trailers. In fact, as long as the dump trailer is equipped with the necessary safety structure configuration, the safety is still very guaranteed.

Brake configuration

The weight of the dump truck trailer is heavy, and the long braking distance has been criticized, especially after the heavy load, it will be more difficult for the vehicle to brake. YUHANG brand dump trailers have been greatly upgraded in this respect. It uses larger brake pads of 410mmx200mm (regularly 400mmx150mm), and is equipped with an ABS anti-lock braking system, which shortens the braking distance of the vehicle and improves safety performance.

Tire pressure detection configuration

Tires are the only part of the vehicle in contact with the ground. Changes in the tire pressure of the vehicle will affect the fuel economy and safety of the vehicle. If the tire pressure is not within the normal range, it may cause increased fuel consumption or tire blowout accidents. The TPMS tire pressure detection system can help drivers know the tire pressure of the vehicle at any time, so as to make timely adjustments to avoid losses caused by excessively high or low tire pressure, and the vehicle will run more safely.

Anti-rollover configuration

Dump trailer rollover is a common traffic accident. If the driving situation is complicated in rainy or snowy days, problems are more likely to occur. The front and rear axles of the YUHANG dump trailer are respectively equipped with anti-rollover stabilizer bars, which greatly improves the safety performance, and there is also a horizontal double hydraulic shock absorber under the cab, which can also prevent the vehicle from rolling over.

11. Common problems and solutions in the process of using dump trailers

Let’s take a look at the common problems and solutions of dump trailers:

(1) Why press the lift switch on the instrument panel, the car is lowered; press the down switch on the instrument panel, the car is lifted?

Answer: This is because the solenoid valve controlling the lifting and lowering is reversed. There are three ways to eliminate: ① swap the wires of the lift and lower switches on the dashboard; ② swap the wires of the solenoid valve that controls the lift and drop; ③ swap the two air pipes of the distribution valve.

(2) The dump semi trailer does not lift?

Answer: The dump semi-trailer does not lift and the following components should be checked.

Power take-off: first check whether the transmission shaft connected to the oil pump rotates. If it does not turn, it means that there is a problem with the power take-off (the solenoid valve of the power take-off or the power take-off itself); if it turns, it means that there is no problem with the power take-off, and other parts should be further checked.

Oil pump: ① Whether the rotation direction of the oil pump is correct. Stretch out the left hand, the thumb is facing the spline of the oil pump, and the rotation direction of the other fingers is the same, it is a left-handed pump, otherwise it is a right-handed pump. ② Whether the oil pump is damaged. If the oil pump is worn out, the high and low pressure chambers of the oil pump will be connected, making it impossible to pump oil.

Distribution valve: ① Check whether there is air in the air pipe on the distribution valve. Press the lift and lower switch to see if there is air in the two air pipes on the distribution valve. If there is no air, it means that the solenoid valve controlling the lifting and lowering is faulty, and the solenoid valve should be replaced. ② Whether the distribution valve is damaged.

(3) Is the lifting speed of the carriage adjustable, and is it a fault that the automatic lowering is faster?

Answer: The lifting speed cannot be adjusted. If the lifting speed is too fast, it is a fault phenomenon and should be checked in time.

(4) What are the important components of the hydraulic lifting system, and what are their functions?

Answer: Oil pump—oil supply; one-way valve—controls the flow of oil; distribution valve—controls the lifting and lowering of the carriage; oil cylinder—produces thrust.

(5) Why does the gear pump have “tooth beating” phenomenon? How to exclude?

Answer: Sometimes when the PTO takes power, the gear pump makes a rapid “click, click… sound”, which is mostly caused by insufficient oil intake of the oil pump. This phenomenon of the new semi dump trailer may be caused by the oil inlet pipe of the oil pump being too thin or the oil inlet pipe being sucked. The oil inlet pipe should be thickened and the oil inlet pipe with higher strength and hardness should be used. The dump truck trailer that has been used for a period of time may be caused by the aging of the oil inlet pipe and the suction, or the filter screen of the oil outlet of the oil storage tank is blocked, resulting in poor oil inlet. If all possibilities are ruled out, the oil pump is only damaged and should be replaced in time.

12. How to properly maintain our dump semi trailer?

Semi dump trailers are special vehicles that unload cargo by themselves through hydraulic or mechanical lifting, and require frequent maintenance. In order to prolong the service life and working performance of the trailer, the following will give you a detailed introduction to the maintenance knowledge of dump trailers.

1. To maintain the hydraulic system of the tipper semi trailer, the impurities inside the hydraulic oil tank must be cleaned before changing the oil, and the oil must be kept clean at all times and replaced regularly. If there are impurities in the operation of the hydraulic system, they will enter the valve group and the oil cylinder along with the pipeline, which will cause the valve group to get stuck or damage the seal in the oil cylinder, affecting the normal use of the lifting system.

2. Regularly test the battery of the dump truck trailer to check whether the battery is firm and whether the electrolyte is within the normal range. It is also necessary to check the tires of the vehicle, and check the tire pressure of the vehicle at room temperature. If it is lower than the normal standard, the tire pressure should be replenished in time.

3. Always check whether the parts of the vehicle are damaged or missing, and check whether each screw is fastened one by one to protect the safe operation of the vehicle.

4. Regularly check whether the retarder is working normally, and whether there is any hidden danger in the meshing of the connecting rod gear.

5. Since the chassis of the trailer is close to the ground, it is inevitable that there will be sewage splashed on the chassis when passing through some puddles or muddy puddles, and the stones on the road will also form a certain external impact on the chassis, which will cause damage to the chassis over time. Therefore, we must pay attention to the cleaning and anti-rust treatment of the vehicle chassis, and repair it immediately when the chassis is found to be damaged.

6. The acidic substances in the rainwater will cause strong corrosion to the metal surface of the vehicle and accelerate the damage of the dump trailer. Therefore, the vehicle body can be waxed and glazed to form a dense protective film on the surface to avoid rain erosion.

13. How to buy a qualified tipper trailer?

First, we need to determine whether the semi dump trailer waiting to be purchased is up to the job. You can tell YUHANG the type and load level of the goods that need to be transported, and we will provide you with professional advice.

Second, refer to the local laws and regulations of the country and use whether there are clear loading weight restrictions and regulations on dump semi-trailers. This is very important, and it is related to whether the dump trailer can successfully have a license plate and put it into work.

Third, what is the working environment and road conditions of the dump trailer? Because bad road conditions and flat road conditions have different configuration requirements for dump trailers. According to the conditions, we need to make some adjustments to ensure that the dump truck can serve you better.

Fourth, you need to inform the sales manager about the detailed technical data of the dump trailer, and then we will confirm the specific specifications, trailer drawings and price range for you.
